Screen tripper 10
Portable electronic equipment 20
Time is provided with unit 112
Embodiment
Please refer to Fig. 1, in the preferred embodiments of the present invention, portable electronic equipment 20 comprises a touch screen 22 with touch function.When the user used portable electronic equipment 20, the general object of oneself habitually practising of using knocked touch screen 22 to operate.Object can cause that to knocking of touch screen 22 portable electronic equipment 20 produces the frequency discernible signal, as, cause vibration that portable electronic equipment 20 is produced or the sound that is sent by knocking.
Preferred embodiments screen tripper 10 of the present invention comprises a central processing unit 100 and sensor 200 that is arranged in the portable electronic equipment 20.Central processing unit 100 comprises a processing unit 102, be connected to the screen control module 104 of processing unit 102, a frequency detecting unit 108 and a timing unit 110.In this embodiment, sensor 200 is the vibration transducers that are used for sense vibrations, and it is arranged on touch screen 22 back sides central authorities of (figure does not show).Be appreciated that sensor 200 also is used for the sound transducer of sensing sound, it is arranged on the corner at touch screen 22 back sides.
The frequency of the frequency discernible signal that portable electronic equipment 20 is produced is different because of the difference of knocking thing; Use habitual object to knock touch screen 22 because the user is general; And the variation range of the frequency of the frequency discernible signal that object produced that should be habitual is less; Therefore, detect this frequency and whether can prevent in setting range that the habitual thing of other non-user from possibly cause the release of touch screen 22 to the maloperation of touch screen 22.
In this embodiment, the user uses finger tapping touch screen 22.The setting range of the frequency of this frequency discernible signal is 50 to 550 hertz.So, can prevent to knock the release of object the cause touch screen 22 of frequency outside 50 to 550 hertz of the frequency discernible signal of generation like pen etc.
When processing unit 102 receives first knocking, first frequency acknowledge signal, second knocking, time acknowledge signal and second frequency acknowledge signal according to time sequencing after; Transmit a unlocking signal to screen control module 104, with control screen control module 104 release touch screen 22.
When the user wants release touch screen 22, carry out double knocking to touch screen 22 with finger.After knocking for the first time, screen control module 104 knocks the back and sends first knockings to processing unit 102 detecting.At this moment, processing unit 102 sends first trigger pip to timing unit 110, so that timing unit 110 picks up counting.Simultaneously; Processing unit 102 is gone back controlled frequency detecting unit 108 and is obtained the frequency that this knocks the frequency discernible signal that makes portable electronic equipment 20 generations for the first time through sensor 200, and first frequency acknowledge signals are sent to processing unit 102 in frequency detecting unit 108 these frequencies of judgement back in setting range.
After knocking for the second time, screen control module 104 knocks the back and sends second knocking to processing unit 102 detecting equally.At this moment, processing unit 102 sends second trigger pip to timing unit 110, so that timing unit 110 stops timing.The time interval that timing unit 110 judgements are knocked for this twice with after interior, is sent a time acknowledge signal to processing unit 102 at setting-up time.Simultaneously; Processing unit 102 controlled frequency detecting unit 108 again obtains the frequency that this knocks the frequency discernible signal that makes portable electronic equipment 20 generations for the second time through sensor 200, and second frequency acknowledge signal sent to processing unit 102 in frequency detecting unit 108 these frequencies of judgement back in setting range.At this moment, processing unit 102 transmits a unlocking signal to screen control module 104, and screen control module 104 receives release touch screen 22 behind this unlocking signal.
Preferably, central processing unit 100 comprises that also a time that is connected to processing unit 102 is provided with unit 112 and frequency configuration unit 114.Time is provided with unit 112 and allows the user through touch screen 22 this setting-up time to be set, to change the qualification in the double time interval of knocking, to adapt to the custom of knocking of different user.Frequency configuration unit 114 allows users through touch screen 22 setting range of the frequency of this frequency discernible signal to be set, and uses the different objects of habitually practising to knock the custom of touch screen 22 to adapt to different families.
Please combine Fig. 2, the screen unlock method of preferred embodiments of the present invention may further comprise the steps:
S101: whether the touch screen with touch function that detects portable electronic equipment receives is knocked for the first time, if not, continue to detect, if, detect this knock for the first time make that this portable electronic equipment produces the first time frequency discernible signal frequency;
S102: whether the frequency of judging this of frequency discernible signal in setting range first time; If not, return step S101, if, detect in the time of setting, whether this touch screen receives is knocked for the second time; If not, return step S101, if, detect this knock for the second time make that this portable electronic equipment produces the second time frequency discernible signal frequency;
S103: whether the frequency of judging this of frequency discernible signal in setting range, if not, returns step S101 second time, if, the touch screen of opening this portable electronic equipment.
Those skilled in the art will be appreciated that; Above embodiment only is to be used for explaining the present invention; And be not to be used as qualification of the present invention; As long as within connotation scope of the present invention, appropriate change that above embodiment did is all dropped within the scope that the present invention requires to protect with changing.
